2 Claims.

This invention relates generally to lamps or lanterns of the type provided with fonts for the reception of kerosene or other liquid fuel which is burned in the use of the lamps or lanterns, 5 and more specifically to lamps or lanterns of the type employed for giving signals by moving same about, as, for instance, in accordance with the practice followed in the operation of railroad trains, the predominant object of the invention 19 being to provide an improved font which is so constructed and arranged that such splashing about of the liquid fuel, when the lamp or lantern is moved about in giving signals, as would extinguish the light-producing flame of the lamp T or lantern is prevented.

Fig. l is a view illustrating my improved font in vertical section and showing a burner associated therewith.

Fig. 2 is a cross-section on line 2-2 of Fig. 1.

In the drawing, wherein is shown for the purpose of illustration, merely, one embodiment of the invention, A designates the improved font generally. The font A includes an outer shell providing an annular side wall 1 and a bottom wall 2, the top wall 3 of the font, in the embodiment of the invention illustrated in the drawing,

being provided by a separate element which is secured in any suitable manner to the annular side wall, as shown in Fig. 1. At the approximate diametrical center of the top wall 3 a tapered 7 a raised annular head 6 is present at the point where the top wall 3 and the downwardly extended, annular flange .5 meet.

Any suitable burner may be associated with the font A, the particular burner B illustrated in the drawing being provided with a tapered lower portion B which is introduced into the correspondingly tapered opening 4 and is held in place by the frictional grip between said burner portion B of the burner and the tapered, downwardly extended flange 5. The burner B has associated with it the usual wick W, and also said burner structure includes means C for adjusting the wick with respect to theburner. Secured to the top wall 3 of the font A at the lower or inner face thereof is an elongated tapered tube '7. The elongated, tapered tube '7 is open at its lower end, as shown in Fig. 1, and said open end of said tube is spaced upwardly a slight distance from the bottom wall 2 of the font. At a point adjacent to the upper end of the tube 7 the wall of said tube is provided with diametrically opposed apertures 8 which provide vent openings for the main body of the font when liquid fuel is being introduced into the font. As shown clearly in Fig. 1, the tapered tube 7 receives the major portion of the wick W of the burner when the improved font is in use.

In the use of a lamp or lantern provided with my improved font a relatively small body of liquid fuel is trapped within the tapered tube '7, in which body of fuel the wick Wis submerged, and because of the tapered shape of said tube the volume of liquid fuel within said tube is reduced to a minimum. Because of this situation the moving about of the lamp or lantern in giving signals will not result in the light-producing flame at the burner being extinguished due to the fact that the small body of liquid fuel within the tube 7 will not receive sufficient splashing action to accomplish this undesirable result. The body of liquid fuel within the main body of the font will be splashed about by signal-giving movements of the lamp or lantern, but this body of liquid fuel is maintained remote from the burner by the tube 7, hence the splashing about of -the liquid fuel within the main body portion of the font will not interfere in any manner with the operation of the burner. It is apparent, of course, that because the lower end of the tube '7 opens into the main body of the font A the levels of the bodies of liquid fuel within said tube and said main body of the font will be uniform at all times.

I claim:

1. A font of the class described comprising a main body portion in the form of an outer shell having a top wall provided with a tapered opening adapted to receive a portion of a burner having a wick associated therewith, said tapered opening being produced by a downwardly extended flange portion formed on said top wall, and a tapered tube fixed to said top wall of said outer shell at said opening therein and having said downwardly extended flange portion of the top wall extended into its upper end, said tapered tube being adapted to receive said wick and being provided with an open lower end which is spaced upwardly from the bottom wall of the main body portion of the font whereby said tapered tube is arranged in communication with the main body portion of the font so that liquid fuel introduced into the font will rise to the same level in the main body portion and tapered tube, said tapered tube being provided with a horizontally disposed, annular flange at its upper end which contacts with the lower face of the top wall of said main body portion and having apertures formed in the wall portion thereof adjacent to the upper end of said tapered tube.

2. A font of the class described comprising a main body portion in the form of an outer shell having a top wall provided with a tapered opening adapted to receive a portion of a burner having a wick associated therewith, said tapered opening being produced by a downwardly extended flange portion formed on said top wall, a tapered tube fixed to said top wall of said outer shell at said opening therein and having said downwardly extended flange portion of the top wall extended into its upper end, said tapered tube being adapted to receive said wick and being provided with an open lower end which is spaced upwardly from the bottom wall of the main body portion of the font whereby said tapered tube is arranged in communication with the main body portion of the font so that liquid fuel introduced into the font will rise to the same level in the main body portion and tapered tube, said tapered tube being provided with a horizontally disposed, annular flange at its upper end which contacts with the lower face of the top wall of said main body portion and having apertures formed in the wall portion thereof adjacent to the upper end of said tapered tube, and a raised burner-receiving portion formed at the top surface of said top wall adjacent to the junction of said top wall and the downwardly extended flange portion thereof.
